What is the compression ratio achieved with these pistons?

These Mahle MS pistons are designed with a 35cc dish volume to achieve an 11.4:1 compression ratio. This is dependent on the cylinder head volume and head gasket thickness used in your specific engine build.

Are these pistons suitable for all 3.6L to 3.9L engines?

These pistons are specifically designed for 3.6L to 3.9L displacements and feature a 102mm bore. It is crucial to verify compatibility with your specific engine block, crankshaft, connecting rods, and cylinder heads to ensure proper fitment and performance.

What is included in this set?

This set includes six Mahle MS pistons. Wrist pins are typically included with Mahle piston sets, but it is recommended to confirm the exact contents with the product listing or manufacturer specifications before purchase.

Product Details

Forged from high-strength aluminum alloy, these Mahle MS pistons are built to handle the demands of a performance engine rebuild. With a 102mm bore and a 35cc dish volume, they are designed to achieve an 11.4:1 compression ratio when paired with the correct cylinder heads and gasket combination for 3.6L to 3.9L displacement engines. The 80.4mm stroke and 127mm rod length are key dimensions that determine the piston's position in the cylinder bore throughout its travel, impacting engine timing and performance characteristics.

This set includes six pistons, each featuring a 23mm wrist pin diameter, a common size for many performance applications. Mahle's expertise in piston manufacturing means these components are well-made and balanced for smooth operation. The forged construction offers improved durability and resistance to detonation compared to cast pistons, making them a solid choice for builds where reliability under stress is paramount. Proper installation and balancing are crucial for optimal performance and longevity.

Please note that this piston set is not CARB approved and cannot be shipped to California. It's important to verify compatibility with your specific engine block, crankshaft, connecting rods, and cylinder heads to ensure a proper fit and achieve your desired compression ratio and performance goals. Refer to Mahle's installation guidelines for detailed specifications and recommendations.
